오암석 한국정보통신학회 2023 Journal of information and communication convergen Vol.21 No.3

Owing to the environment in which it has become difficult to face people, on-tact communication has been activated, and onlinevideo conferencing platforms have become indispensable collaboration tools. Although costs have dropped and productivity hasimproved, communication remains poor. Recently, various companies, including existing online videoconferencing companies,have attempted to solve communication problems by establishing a videoconferencing platform within the virtual reality (VirtualReality) space. Although the VR videoconference platform has only improved upon the benefits of existing video conferences,the problem of manually summarizing minutes because there is no function to summarize minute documents still remains.Therefore, this study proposes a method for establishing a meeting minute summary system without applying cases to a VRvideoconference platform. This study aims to solve the problem of communication difficulties by combining VR, a metaversetechnology, with an existing online video conferencing platform.

The VR / AR market has grown significantly due to the development of virtual reality and augmented reality in thecore technology field of the 4th Industrial Revolution. Since VR is basically focused on space and time, and the humanbrain is very sensitive to temporal events, it is important to make accurate I / O interface technology, one of the virtualreality technologies, not to affect the brain's cognitive ability. VR depends on the technology of the hardware such as thedisplay and the sensor for biometric signal recognition. In this paper, in order to prevent the sensitive brain from affectingthe sensor device in consideration of hardware dependency of VR, it is necessary to make various corrections to lowerthe motion to photon (MTP) to 20m / s or less experiments on the method and filtering were carried out. 4차 산업혁명의 핵심 기술 분야의 가상현실(Virtual Reality)과 증강현실(Augmented Reality)의 발달로 인해VR/AR시장이 크게 성장하였다. VR은 기본적으로 공간과 시간에 초점을 맞추고 있고, 인간의 두뇌는 시간적 사건에매우 민감하기 때문에 두뇌의 인지능력에 영향을 주지 않기 위해선 가상현실 기술 중 하나인 입출력 인터페이스 기술을 정확하게 만드는 것이 중요하다. VR은 디스플레이와 생체신호인식을 위한 센서 등 하드웨어의 기술의존도가상당하다. 본 논문에서는 VR의 하드웨어 의존도를 고려해 센서 디바이스를 이용하여 민감한 두뇌에 영향을 끼치지않기 위해 사용자 움직임이 디스플레이 화면에 완전히 반영되는 시간 MTP(Motion to Photon)을 20m/s 이하로 낮추기 위한 여러 가지 보정방법과 필터링에 대한 실험을 진행하였다.

오암석,이준연 동명정보대학교 2002 저널 정보공학기술 Vol.1 No.-

The Internet has been the pipeline through which online communication, transactions and business operations are possible, but a lot of dangers have arisen from it in spite of its positive effects on information society. It is the problem of information security that hinders the growth and utilization of the Internet. There are three factors that matter in protecting information : physical, administrative and technical. Among them, the technical factor is increasingly important. Thus, the PKI encryption system is crucial for the security of business operations, commerce and financial business. PKI refers to the users key management and inter-CA certification structure. For a few years ahead, PKI will have to equipped within a global framework since business operations and commerce will be carried out globally through the Internet. By providing the web services based on the system which this research aims to develop, the user can given a more secure system without any additional cost. Out system will be designed to provide the PKI length up to 2048 bits. The real-time drawing and management of certificates is possible, thus maximizing the operational efficiency. The proposed system in this research is directly applicable to intranet environments and small shopping malls devoid of security systems, enabling them to provide more secure services. The user can also avoid illegal attacks in the cyberspace and protect his/her data by utilizing user privacy and electronic signature provided by the high-level encryption of our system. Since our system is Linux-based, it should be highly competitive both in price and functionality. Designed to allow both CA and the user to generate electronic key signature, it is also expected to be very efficient.

오암석 동명정보대학교 2000 東明情報大學校論文集 Vol.3 No.-

Nowadays, the broadening of users of Internet to general public and the generalization of information sharing through the Web, more importance is given to Internet which may increase the official efficiency in the enterprise and provides the instant service of necessary information through the Web. However, though some cases of Intranet construction in some companies have proven the efficiency of Intranet, most companies are still reluctant to introduction of Intranet because of the cost and security problem. Therefore, when more systematic security system is designed, the data and users of Internet are managed in real time, and the differentiating service for the users is developed easily on the Web, it will be in short time to establish the network of Intranet among enterprise. In this paper, we propose an intranet solution for the small-to-middle sized companies, SIGMA, in which every management process is possible on the Web and the separate information service for each group, and for each person is provided. And, to differentiate our solution from existing ones, we provides the manager interface by which the management on the Web is possible and the constructional plan of Intranet solution for the enterprise in low price.

VR 환경을 고려한 동작 및 위치 인식에 관한 연구

오암석,Oh, Am-suk 한국정보통신학회 2017 한국정보통신학회논문지 Vol.21 No.12

본 논문에서는 체험형 VR 환경을 고려한 동작 및 위치 인식 기법을 제안한다. 동작 인식은 신체부위에 복수개의 AHRS 디바이스를 부착하고 이를 기준으로 좌표계를 정의한다. 각각의 AHRS 디바이스로부터 측정되는 9축 움직임 정보를 기반으로 사용자의 동작을 인식하고 신체 분절 간의 관절각을 추출하여 동작을 보정한다. 위치인식은 AHRS 디바이스의 관성센서를 통해 보행 정보를 추출하여 상대위치를 인식하고 BLE Fingerprint를 이용하여 누적오차를 보정한다. 제안하는 동작 및 위치인식 기법의 구현을 위해 AHRS기반의 위치인식과 관절각 추출 실험을 진행하였다. 위치 인식 실험의 평균 오차는 0.25m, 관절 각 추출 실험에서 관절 각 평균 오차는 $3.2^{\circ}$로 나타났다. In this paper, we propose a motion and position recognition technique considering an experiential VR environment. Motion recognition attaches a plurality of AHRS devices to a body part and defines a coordinate system based on this. Based on the 9 axis motion information measured from each AHRS device, the user's motion is recognized and the motion angle is corrected by extracting the joint angle between the body segments. The location recognition extracts the walking information from the inertial sensor of the AHRS device, recognizes the relative position, and corrects the cumulative error using the BLE fingerprint. To realize the proposed motion and position recognition technique, AHRS-based position recognition and joint angle extraction test were performed. The average error of the position recognition test was 0.25m and the average error of the joint angle extraction test was $3.2^{\circ}$.

오암석 울산과학대학 1995 연구논문집 Vol.20 No.-

공장관리 모듈들은 배치 작업으로서 비동기적으로 처리되며 각 모듈에서 관리하는 데이타간에 다양한 종속관계가 존재한다. 따라서 이러한 환경에서는 동시작업시의 일관성 유지문제가 해결되어야 한다. 이 논문에서는 공장관리 모듈들이 동시에 실행될 때 모듈간의 데이타 교환과 입출력 데이타간의 종속적인 관련성에 따른 일관성 유지 기법을 제시한다. 이 기법은 규칙과 메시지 전송 프로토콜을 이용하여 다양한 종속관계를 표현하고 자동적으로 일관성을 유지한다. Factory management modules are asynchronously proceeded in batch job and various dependency relationship exists in data which each module manages. Therefore, under these environments, the consistency maintenance problem of concurrent processing should be resolved. This paper is aimed to present consistency maintenance mechanism for data exchange among modules and dependent relationship between input and output data when factory management modules are executed concurrently. This mechanism represents various dependency relationships and maintains consistency automatically by using rule and message transfer protocol.

오암석 한국정보통신학회 2022 Journal of information and communication convergen Vol.20 No.4

Owing to the need to establish a cooperative-intelligent transport system (C-ITS) environment in the transportation sector locally and abroad, various research and development efforts such as high-tech road infrastructure, connection technology between road components, and traffic information systems are currently underway. However, the current central control center-oriented information collection and provision service structure and the insufficient road infrastructure limit the realization of the C-ITS, which requires a diversity of traffic information, real-time data, advanced traffic safety management, and transportation convenience services. In this study, a network construction method based on the existing received signal strength indicator (RSSI) selected as a comparison target, and the experimental target and the proposed intelligent edge network compared and analyzed. The result of the analysis showed that the data transmission rate in the intelligent edge network was 97.48%, the data transmission time was 215 ms, and the recovery time of network failure was 49,983 ms.
